Reland "Vulkan: Reactivate already started render pass when possible" This is a reland of commit ad9537af7f2bb5e22bc73f4e833fd3789adaa217 Original change's description: > Vulkan: Reactivate already started render pass when possible > > In some usage case (such as lineage_mobile), we are seeing in the middle > of render pass, app switch to another fbo just to issue a glClear() > call, which the clear call itself gets deferred. Application then switch > back to the original frame buffer. Before this CL, the render pass gets > recreated due to frame buffer binding change, even though the clear gets > deferred and new render pass and the previous render pass are > essentially the same. This CL detects this situation and reactivate the > current render pass instead of creating a new one. With this CL, > lineage_m app trace reduces frame time from 3.86ms to 3.7ms, and only > one render pass is used instead of two. > > This CL also allows the render pass started by BlitFramebuffer reused by > subsequent draw calls. Asphalt_9 is hitting this use pattern and this CL > reduces frame time by 0.1245 ms (from 5.6203 ms to 5.4958 on pixel 7 > pro) > > Bug: b/273808966 > Change-Id: I48c2671cbef3ff9d6cf59caae88c37c77828ee07 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4348713 > Reviewed-by: Amirali Abdolrashidi <abdolrashidi@google.com> > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> > Commit-Queue: Charlie Lao <cclao@google.com> Bug: b/273808966 Change-Id: Ice9062122ae320b1a0108ff981bc65bd13b2ada0 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4406888 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Charlie Lao <cclao@google.com> Reviewed-by: Amirali Abdolrashidi <abdolrashidi@google.com>
